Profile MCP Server

profile-mcp

Personal MCP server for kazejev.com. The server operates on Cloudflare Workers. The server is read-only: it gives a biography, skills, projects and contact links to AI agents. The server has no runtime dependencies.

Language

This project uses Simplified Technical English (ASD-STE100). Write all documentation and all code comments in this style:

• Keep sentences short. Use a maximum of 20 words for an instruction.
• Use the active voice.
• Use one word for one meaning. Use the same word for the same thing.
• Write one instruction in one sentence.

Protocol support

The server supports two protocol eras.

The MCP 2026-07-28 revision removed the initialize handshake. It also removed the protocol-level sessions. Thus a server for the new revision is very different from a server for the older revisions. Most clients still use the older revisions. Therefore this server supports the two eras on one endpoint.

The server selects the era for each request. If the MCP-Protocol-Version header shows a modern version, the server uses the modern rules. If it does not, the server uses the legacy rules.

The modern era has these rules:

• The server sends 405 for a GET request and for a DELETE request. The GET stream and the session teardown are no longer in the protocol.
• The client must send the Mcp-Method header. For tools/call, resources/read and prompts/get, the client must also send the Mcp-Name header.
• If a header value disagrees with the body value, the server sends 400 and error code -32020 (HeaderMismatch). The server first decodes the =?base64?…?= format, then compares the two values.
• If the server does not support the protocol version, the server sends 400 and error code -32022. The error data shows the supported versions.
• If the method is unknown, the server sends 404 and error code -32601. A client uses this response to identify a modern server.
• A list result contains ttlMs and cacheScope. Each result contains resultType.

The server does not have subscriptions/listen, the MRTR input requests, or the tasks extension. The server does not need them, because each tool is static and has no arguments.

Endpoint

POST /mcp. The server sends 404 for all other paths.

Files

src/content.ts    All personal content. You change this file frequently.
src/protocol.ts   The MCP methods. This file is independent of the transport.
src/index.ts      The Cloudflare Worker entry point.
test/smoke.mjs    The protocol tests.

Development

npm install
npm run typecheck
npm test          # Compiles the code, then does the tests.
npm run dev       # Starts wrangler dev.

Deployment

npx wrangler login
npx wrangler deploy

Then add the custom domain mcp.kazejev.com in the Cloudflare dashboard. Go to Workers & Pages, then this Worker, then Settings, then Domains & Routes.

Server card

The repository theglobe/theglobe.github.io sends a discovery card at /.well-known/mcp/server-card.json. The protocolVersion field and the transport.endpoint field in the card must agree with this server.

The card gives the server name kazejev-personal. This name is different from the repository name and from the Worker name. Do not change SERVER_NAME in src/content.ts unless you also change the card.

To do

• Put the correct biography, skills and projects in src/content.ts.
• Make a decision about a contact email address. The file has no email address.

Registry

The server is in the official MCP Registry as com.kazejev/profile.

https://registry.modelcontextprotocol.io/v0/servers?search=kazejev

server.json holds the registry entry. To publish a new version, change the version field to match SERVER_VERSION in src/content.ts, then:

mcp-publisher login dns --domain kazejev.com --private-key <HEX>
mcp-publisher publish

The namespace com.kazejev is proved by a TXT record on kazejev.com:

v=MCPv1; k=ed25519; p=Z3Hxdi1IjSf8w1F4nnlcPJHX/X72+rsaXY4DTJJj5Ns=

That record must stay in place. The matching private key is not in this repository. To use a different key, generate a new pair and replace the TXT record with the new public key.
